Answer:

  1

Step-by-step explanation:

The right triangle is isosceles, so x = 45° and tan(x) = 1.

__

You can determine tan(x) either from your knowledge of trig function values, or from the fact that the two legs of the triangle are of equal length. The tangent is the ratio of the opposite leg to the adjacent one. When those legs are the same, the ratio is 1.

Answer:

11) -104÷8=x

-13=x

x=-13

12) b=-56÷14

Answer:

£2.6

Step-by-step explanation:

Given data

3 packs of potatoes costing £3 each= 3*3= £9

3 packs of carrots for £2 per pack= 3*2= £6

4 turnips costing 60p each= 4* 0.60= £2.4

Hence the total cost = 9+6+2.4= £17.4

Hence the change will be 20-17.4

= £2.6

Answer:

y = 2

Step-by-step explanation:

Given

[tex]\frac{2y-1}{15}[/tex] = [tex]\frac{y}{10}[/tex] ( cross- multiply )

10(2y - 1) = 15y ← distribute left side

20y - 10 = 15y ( subtract 15y from both sides )

5y - 10 = 0 ( add 10 to both sides )

5y = 10 ( divide both sides by 5 )

y = 2

Answer:

Step-by-step explanation:

First replace f(x) with y

[tex]y=-2x+2[/tex]

Then switch the variables

[tex]x=-2y+2[/tex]

Solve for the new y value

[tex]x-2=-2y\\[/tex]

[tex]-\frac{x-2}{2} =y[/tex]

x: número más grande

y: número menor

3 (x + y) = 63

x = 6 años

Sustituimos la x = 6y de la segunda ecuación en la primera

3 (6 años + años) = 63

7 años = 63/3

3 años = 21

y = 21/7

y = 3

Este es el número más pequeño y = 7, por lo que el número más grande es x = 6y = 6 * 3 = 18

El número más grande es 18

The transformation that maps the pre-image (ΔA) to the image (ΔA') will be done by a rotation 90° counterclockwise around the origin. Then the correct option is C.

A spatial transformation is each mapping of feature shapes to itself, and it maintains some spatial correlation between figures.

Rotation does not change the size and shape of the geometry.

Answer:

1:144

Step-by-step explanation:

if each floor is 15 feet, the whole building is 60 feet tall. so it does have a scale of 5 inches:60 feet but if you simplify that, its 1 inch: 12 feet, so you convert feet into inches by multiplying by twelve, which gives you a scale of 1:144 inches

Answer:

According to Charles' Law the order of arrangement of the location where the balloon has the smallest size to the location where the balloon has the largest size is given as follows;

A freezer < A cold refrigerator < A normal room temperature classroom < A warm cupboard

Step-by-step explanation:

The parameter of the balloon Katie blows are;

The amount of air in the balloon = Fixed (constant)

The initial size of the balloon = The length of the measured string

The locations in which the balloon can be placed = A freezer, a warm cupboard, a cold refrigerator, a normal temperature classroom

The size of the balloon is given by the volume of the balloon

according to Charles' Law, the volume of a given mass of gas is directly proportional to its temperature

Mathematically, Charles law can be expressed as follows;

V ∝ T

Therefore, as the temperature to which the balloon is subjected decreases, the volume decreases

The locations arranged in order of increasing temperature is given as follows;

Freezer < Cold refrigerator < Normal temperature classroom < Warm cupboard

Given that Katie blow's the balloon in a normal temperature classroom, according to Charles Law, we have;

The temperature of the air in the balloon decreases largely in a freezer, therefore, the size of the balloon largely decreases

The temperature of the air in the balloon increases in a warm cupboard, therefore, the size of the balloon increases

The temperature of the air in the balloon decreases slightly in a cold refrigerator, therefore, the size of the balloon decreases

The temperature of the air in the balloon remains the in a normal temperature classroom, therefore, the size of the balloon remains the same

The size of the balloon reduces the most in a freezer

The size of the balloon increases in a warm cupboard

The size of the balloon decreases slightly in a cold refrigerator

The size of the balloon remains the same in a normal temperature classroom.

Answer:

Step-by-step explanation:

The initial position of the submarine was 600 ft below sea level

Then it ascends, i.e., goes up or moves up 250ft.

So now it is (800–250=)550 ft below sea level. I hope this helps.

Answer:

Slope = [tex]\frac{1}{2}[/tex] , X-intercept = 8 , Y-intercept  = -4

Step-by-step explanation:

the following equation is given in slope intercept form which is y = mx + b where m is the slope and b is the y intercept

since m = [tex]\frac{1}{2}[/tex] and b = -4, we can say our slope is [tex]\frac{1}{2}[/tex] and y intercept is -4.

Recall that x intercept occurs when y = 0 so plug y = 0 in the equation then solve for x

0 = [tex]\frac{1}{2}[/tex]x - 4

add 4 to both sides,

4 = [tex]\frac{1}{2}[/tex]x

multiply by 2 on both sides,

4*2 = x

8 = x

x = 8

so our x-intercept is 8
